The pressure plate is held with the ends of the screws 12 in engagement with the block 3 by a weighted body 39 and a cord 38 trained on a roller 37 and attached to said pressure plate.

In a slot 18 a. two-armed lever 19 is rockingly mounted the arms of which are formed with longitudinal slots 20 and 21. The slot 20 engages the pin 17 of the lever 16, and the slot 21 engages a pin 24'flxed toa rotary disk23 adapted to be rotated by a spring motor 22. The said.diski.23 is formed with four bores 25, 2 6, 27, 27 which are arranged thereon on a circle and in diametrically i opposite pairs, the bores 27, 27 and 25, 26 of the pairs being located close to each other. The said bores are adapted to be engaged by a locking pin 30, which is acted upon by a spring 28 tending to push the same into engagement with the holes, a and the electromagnet 29 adapted to retract the same from the holes. The coil of the-electromagnet 29 is connected by leads 32 and 33 with a'source'3l of electric energy and aspring-pressed switch 34, 35 which'is normally open, and which is adapted to be automaticaly closed by the small hand 40 of the clock engaging the spring arm 35 ofthe switch. "When the said hand 40 engagesthe spring arm 35 it retracts the same away f'romthe contact 34, and when the spring armis released it is thrown-towardsandinto engagement with the contact 34, from which it is immediately retracted by its spring action. Thus the circuit ofthe electromagnet 29 is temporarily closed and immediately opened again. Thereby a current impulse flows through the electro magnet 29, by which'the locking pin is retracted fromthehole 25, 26, 27 or' 27 in opposifrom the rotary disk 23 to the lever 16 by a twoarmed lever 191 the endsof which have the form of two-pronged forks 201', 211". Shortly beforetwelve oclock at night the parts provided for operating "the arm 14 are in the positions shown in Fig. -3,-the disk 23 being locked in position by the pin SQengaging in the bore 25. By the 'currentimpulse caused by the hand 40 the disk 23 is released from the pin 30, andit is turned anticlockwise and in the-direction of the arrow as by the spring motor 22. Therefore the arm 14 is rocked-to the left and in the direction of the arrow a shown in 3 through the intermediary of the levers 19 and 16. Thus the upper mostleaffof the block 3, for example the leaf shown in Fig; 6and carrying the date September 8, is shifted to the left and away from the pins 4 and 5,;the slots-j9-and 6 bein'g 'opento the'right, while the-next leaf ,for example the leaf shown in Fig17, is held in position on the-pins by the flaps 7, softhat itjcannot be carried along by friction. The disk 231s rotated un'tilthe pin 30 is thrown into engagement, by the spring 28, with the bore 27 and locks the disk'23 in position.

When the hour hand again passes the 12 of the clock, that is at noon, the switch 34, is againmomentarily closed, and the pin 30 is retracted from the bore "27 -and immediately thereafter released again. Now the disk 23 is slightly turned, because the pin 30' immediately engages in the adjacent bore 27, and the parts are in the positions shown in Fig. 4. When the hand again passes the 12, that is at midnight of the next day, the disk 23 is turned until the pin 30 engages the bore 26. Thereby the arm 16 islrockedto the. right and the next leaf, that is the leafshown in Fig. 7, of the block 3 is shifted to the right and removed from the block. When the switch is again operated, that is at noon' of the next day, the pin 30 engages the bore 25 of the disk 23 without removing a leaf from the block.

In the modification illustrated in Figs. 8 to 12, I have shown mechanical means in lieu of the electromagnetically controlled operating mechanism for the disk 23. As shown in the said figures in the front wall 80 of a casing 41 a clock 42 is mounted (Figs. 8 and 9). The hour hand 43 of the said clock is fixed to a sleeve 44 mounted concentrically of the arbor 45 of the minute hand 46,the said sleeve and arbor being connected by a gearing 47, 48,47 and 48 as is known in the art. To the sleeve 44 a cam 49 is secured which takes the form of a bail extending longitudinally of the axis of the sleeve. On a screw 50 projecting inwardly from the front wall 80 of the casing 41 a lever 51 is rockingly mounted, which bears on the sleeve 44 and which is adapted to be lifted by and dropped from the bail 49. On a bolt 58 projecting inwardly from the front wall 80 of the casing 41 a lever 54 is'mounted, which is connected with the lever 51 by means of a link 53-jointed to the lever 51 and 52 and engaging the lever 54 substantially at the middle of the arm 54 From the end of the arm 54 'a small weighted body 55 is suspended. To the other arm 54 of the lever 54 alink 57 is pivoted by'means of a' bolt 56. The bottom end of the said link 57 takes the form of a hook 59 which cooperates with a leaf spring 62 secured to a screw '61 fixed totthe front wall 80. 'At its free end the said leaf spring carries a locking nose 64 and it is formed with a slot 63 which is engaged by the hook-shaped end 59 of thelink 57 Below the leaf spring 62 a driving disk is mounted which is parallel to the front wall 80,. The'said driving disk 70 is formed at its circumference with two pairs of notches 65, 66 and67, 68, and it is adapted to be rotated by means of a spring motor 69, the said disk being adapted to be locked in position by the nose 64 engaging in any one of the notches 65, 66, 67 or 68. The pairs of notches 65, 66 and. 67, 68 are diametrically opposite to each other. As is best shown in Fig. 10, the notches 65, 66, 67, and 68 are produced by cuts made in the disk at its circumference and bending the tongues thus produced outwardly. The tongues 95 are usedfor rocking the hook 59. f

To a pin '71 secured to the disk 70 a rod 72 is pivoted which is connected with the downwardly directed arm of a lever 73 rockingly mounted on' a pivot bolt 74 projecting rearsecured to a vertical shaft 77.- The said shaft is rockingly mounted in a bearing 79 carried by a; pressure plate 78 disposed in front of the wall 80, To the bottom end of the said'shaft a gripper' 82 is secured the free-end of which carries a rubber finger 81. The said gripper has a beyond the pressureplate '78'wheii it1isperpendicular to the me es"imam toishift the Q'c'alend'ar leaves the block; of, e d. le vesi j he s; h s be ffi k scribedwithreference toFigs. l'to 71* y l QNear each of-itsfendsftheprefs'sure plateificar ries "a guide roller 83'which is formedwith a circumferential groove pins iiisupport'ing the block 85;:

the .sameinto the casln -ill v The operation of the apparatus follows In the position of the parts ofthe clockflshown in Figs 8 and 9 the ho'urhandis shortly before twelve oiclock'at noon. ,When the hourhand 43 approaches; the 12 on the dial the hailAQfsecured to the sleeve 44: of the hour hand lifts thelever 5i and the link 5 ,1 Thereby, the'lever54 is'rocked in clockwise direction and the link .57, is moved downwardly while slidingingthe slot fi3 of leaf sprirm 52. Ifnow the hour hand 43 exactly indi cates the 12 on the dial, the ball 49 arrives in the position in which the lever 51 is adapted-rapidly to drop therefrom and into initial'position, the downward movement of the lever 5lbeing assist ed by the weightedbody 55. Thus the hook 59 is rapidly pulled upwardly, so'that the nose 64 of the spring 62 is retracted from the notch 66. Therefore the disk '70 is adapted to be advanced in the directionof the arrow 1,! shown'in Fig. 8

by the spring motor ,69. This free movement continues until the tongue 95 of the notch 66 engages the lower end (Fig. 9) of hook 5'7 and shifts the same out of engagem'entwith the leaf spring 62, whereuponthe nose 64 engages the notch 65. During this 'short rotary movement of thedisk '70 the rods '72, '73, '75, '76, 82 perform a small movement which is not'sufi'lcient to cause a leaf to be removed from the block 85. I

At twelve oclock at night the mechanism is loperated in a similar way. But by reason of I the large distance between the notches 65 and '67 the disk is rotated through a larger angle until the said disk is again arrested by the nose engaging in the notch 67. By this large partialrotary movement of the disk 70 aleaf is shifted laterally andaway from the block through theintermediary of the gearing 72,73, 75, 76,82.
